Key facts

Facet joint pain at a glance.

The essentials, in plain English - what it is, how it presents, and how it is confirmed and treated in the UK today.

  • What it is

    Axial neck or back pain arising from the facet (zygapophyseal) joints - the small paired synovial joints at the back of each spinal segment.

  • Types by level

    Cervical (neck plus occipital headache), thoracic (upper back), and lumbar (low back with buttock or posterior thigh referral).

  • Common causes

    Facet osteoarthritis, whiplash and trauma, spondylosis with joint hypertrophy, inflammatory arthritis and spondylolisthesis.

  • Non-radicular

    Pain stays in the trunk rather than travelling into the arm or leg in a dermatomal pattern - a useful distinction from nerve-root pain.

  • Diagnostic test

    Two positive medial branch blocks under image guidance remain the reference test for facet-mediated pain.

  • Gold-standard care

    Radiofrequency ablation of the medial branches gives 6 to 12 months or more of relief when blocks confirm the diagnosis.

Why this guide matters

A structured path from pain to precise treatment.

Facet joint pain is common and treatable, but only if the diagnosis is confirmed properly. The three points below shape everything else on this page.

  • Get the diagnosis right first

    Careful history and examination separate facet pain from disc, nerve-root and stenosis pain - which need different treatment.

  • Blocks confirm the source

    Two positive medial branch blocks under image guidance give confidence that the facet joint is genuinely the pain generator.

  • Ablation gives durable relief

    Radiofrequency ablation of the medial branches typically delivers 6 to 12 months or more of meaningful pain relief.

How the diagnosis is made

From first pain to a confirmed source.

The steps a UK GP, spinal or pain physician will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    Pain history

    Axial, dull and deep, worse with extension, rotation, standing and walking downhill. Morning stiffness is common.

  2. 02

    Assessing

    Focused examination

    Local tenderness over the facet joints, restricted extension and pain reproduction on extension-rotation testing (Kemp’s test).

  3. 03

    Assessing

    Rule out radicular pain

    Careful neurological screen to exclude cervical radiculopathy, lumbar radiculopathy and spinal stenosis before labelling it facet pain.

  4. 04

    Confirming

    Imaging when indicated

    X-ray, CT or MRI to look for facet arthropathy and to rule out fracture, tumour, infection or significant stenosis.

  5. 05

    Confirming

    Red-flag review

    Screen for cauda equina, malignancy, infection and inflammatory back pain before invasive testing.

  6. 06

    Preparing

    Diagnostic medial branch block

    A specialist pain physician injects local anaesthetic around the medial branch nerves under image guidance to confirm the joint as the pain source.

  7. 07

    Preparing

    Confirmatory second block

    A repeat block reduces false positives and, if again positive, supports proceeding to radiofrequency ablation.

Typical timeline: from first assessment to confirmed diagnosis over a few weeks.

Symptoms

What facet joint pain actually feels like.

The classic mix of axial pain, extension-driven stiffness and referred non-radicular symptoms - and the features that mean it is time to escalate.

  • Axial neck or back pain

    Dull, deep pain that stays in the midline or paraspinal region rather than radiating into a limb.

  • Extension and rotation pain

    Symptoms worsen with leaning back, twisting, standing for long periods or walking downhill.

  • Morning stiffness

    A common feature - the spine feels stiff on waking and loosens with gentle movement.

  • Localised tenderness

    Point tenderness over the facet joints, one to two finger-breadths off midline, on palpation.

  • Referred non-radicular pain

    Lumbar facets can refer to the buttock and posterior thigh; cervical facets can refer to the occiput and shoulder girdle.

  • Cervicogenic headache

    Upper cervical facet pain can present as occipital or hemicranial headache with neck stiffness.

  • Post-whiplash pain

    A well-recognised sequel of rear-end collisions - cervical facet joints are commonly implicated.

  • Red flag - suspicious features

    Night pain, fever, weight loss, neurological deficit, saddle anaesthesia or bladder/bowel change need urgent review.

Treatment

How facet joint pain is treated in the UK.

Conservative care first, then image-guided diagnostic blocks and, where confirmed, radiofrequency ablation delivered by a specialist pain team.

  • Specialist physiotherapy

    Core, posture and mobility work - often with Pilates or McKenzie principles - to unload the facets and rebuild control.

  • Analgesia

    Paracetamol, NSAIDs and topical agents first line; neuropathic agents considered where referred pain is prominent.

  • Heat, activity and ergonomics

    Heat, graded activity, workplace and occupational review to reduce sustained extension and rotation load.

  • Diagnostic medial branch block

    Image-guided local anaesthetic block of the medial branch nerves - the confirmatory test for facet-mediated pain.

  • Intra-articular steroid

    Short-term relief in selected patients; evidence for durable benefit is limited compared with radiofrequency ablation.

  • Radiofrequency ablation

    Medial branch RFA denervates the joint and typically gives 6 to 12 months or more of relief - the gold-standard interventional option.

  • Spinal cord stimulation

    Considered in carefully selected patients with persistent, disabling pain despite optimal conventional care.

  • Multidisciplinary pain programme

    Pain physicians, physiotherapy, psychology and CBT alongside graded exercise - especially useful when pain is chronic.

Red flags

When back or neck pain needs urgent attention.

Most axial spinal pain is manageable in primary and specialist care. These are the situations where a same-day or urgent review is needed.

  • Cauda equina syndrome

    Saddle anaesthesia, bilateral leg symptoms, bladder or bowel change - a surgical emergency needing immediate assessment.

  • Progressive neurological deficit

    Worsening weakness, numbness or reflex change - warrants urgent imaging and specialist review.

  • Suspected malignancy

    Night pain, unexplained weight loss, past cancer history or age over 50 with new pain - image early.

  • Suspected infection

    Fever, immunosuppression or intravenous drug use with back pain - rule out discitis or epidural abscess urgently.

  • Fracture risk

    Trauma, osteoporosis or long-term steroid use - consider vertebral fracture with plain films and MRI where needed.

  • Inflammatory back pain

    Insidious onset under 40, prolonged morning stiffness, improvement with exercise - refer for rheumatology assessment.

  • Uncontrolled pain despite conservative care

    Persistent, disabling pain unresponsive to physiotherapy and analgesia deserves a specialist pain opinion.

  • Post-procedural concerns

    New neurology, fever or severe pain after injections or ablation - contact the treating team promptly.

  • Mental-health impact

    Chronic pain and low mood often coexist - flag mood, sleep and function early rather than late.

Living with it

A treatable condition, with a clear ladder.

Four things that make the biggest difference day to day - keep moving, unload the joints, sleep well and know when to escalate.

A quiet reminder

Consistency beats intensity, every time.

Small, steady habits over months do more for the spine than a heroic week that doesn’t last.

  1. 01 Movement

    Keep moving, gently

    Regular, graded activity does more than rest. Walking, swimming and Pilates protect the joints better than a still spine.

  2. 02 Posture

    Unload the joints

    Simple ergonomic changes at work and in the car reduce sustained extension and rotation - a common driver of flares.

  3. 03 Sleep

    Support the neck and low back

    A pillow that keeps the neck neutral and a mattress that supports the lumbar curve makes a real difference to morning stiffness.

  4. 04 Escalate

    Ask about blocks and ablation

    If pain limits life despite good conservative care, a specialist pain opinion about medial branch blocks and RFA is worth having.

Frequently asked

Everything we get asked about facet joint pain.

Quick answers on diagnosis, blocks, ablation and the role of physiotherapy.

  • What is facet joint pain?

    Pain arising from the small paired synovial joints at the back of each spinal segment, called facet or zygapophyseal joints. It is a common cause of axial neck and back pain and is typically dull, deep and worse with extension and rotation.

  • How is facet joint pain different from a trapped nerve?

    Facet pain is non-radicular - it stays in the trunk and can refer to the buttock or occiput but does not travel down the arm or leg in a dermatomal pattern. Radicular pain from a nerve root follows a specific dermatome and often includes neurological signs. Both can coexist and need careful examination to separate.

  • What causes facet joint pain?

    The commonest cause is facet joint osteoarthritis, closely linked to degenerative disc disease. Whiplash and trauma are classic causes in the cervical spine. Inflammatory arthritis, spondylolisthesis, spinal stenosis and post-surgical change also contribute.

  • What is a medial branch block?

    A diagnostic injection of local anaesthetic around the medial branch nerves that supply a facet joint, performed under image guidance by a specialist pain physician. If it reliably abolishes the pain - usually confirmed on a second block - it supports proceeding to radiofrequency ablation.

  • How long does radiofrequency ablation last?

    Medial branch radiofrequency ablation typically gives 6 to 12 months or more of meaningful pain relief when patient selection is right. Nerves regenerate over time, and the procedure can be repeated if pain returns and blocks confirm the source again.

  • Is surgery ever needed for facet joint pain?

    Rarely. Surgery is reserved for specific problems such as instability or severe stenosis rather than for facet pain itself. Most patients do well with a combination of physiotherapy, analgesia, injections and radiofrequency ablation delivered by a multidisciplinary team.
